Ever pay 2 BB's to see what villian is up to?

[checkmate36]

While playing UB .25/.50 full-table I ran into the same situation on 3 different hands. The same villian (calling station) would wait till the turn to raise me. I dumped the first 2 but on the third I felt he was trying to be tricky. I bet the turn, was raised, decided to call the raise and the river bet to see what he was up too.

The flop had JJ7 and I should have known he had the J but felt that after the other 2 hands, I needed to make sure and put my notes on him in order.

I usually don't do this but I did on this session. Thanks for any thoughts.
